Immunomodulatory and pro-oncologic effects of ketamine and isoflurane anesthetics in a murine model.

Introduction: Volatile and intravenous anesthetics may worsen oncologic outcomes in basic science animal models. These effects may be related to suppressed innate and adaptive immunity, decreased immunosurveillance, and disrupted cellular signaling. We hypothesized that anesthetics would promote lung tumor growth via altered immune function in a murine model and tested this using an immunological control group of immunodeficient mice.

Balancing the management of powerline right-of-way corridors for humans and nature.

Green space in electric powerline rights of way (ROWs) can be a source of both ecosystem services and disservices in developed landscapes. Vegetation management within the ROW may influence tradeoffs that maximize potential services or disservices. Frequently mowed ROWs managed as lawn harbor less biodiversity than ROWs with taller vegetation, but may be preferred by people for aesthetic reasons and because they provide space for recreational activities.

Bottlenecks and opportunities for synthetic biology biosafety standards.

The lack of innovative standards for biosafety in synthetic biology is an unresolved policy gap that limits many potential applications in synthetic biology. We argue that a massive support for standardization in biosafety is required for synthetic biology to flourish.

When a pest is not a pest: Birds indirectly increase defoliation but have no effect on yield of soybean crops.

Natural habitats near agricultural systems can be sources of both ecosystem services and disservices on farms. Ecosystem disservices, those aspects of an ecosystem that have negative impacts on humans, may disproportionately affect conservation decisions made by farmers. Birds, in particular, can have complex effects on crops, ranging from positive to neutral to negative.

Survival of the Wealthiest?

A number of promising COVID-19 vaccine candidates may pass approval this month. However, the pandemic will only be brought into check through an equitable, epidemiologically informed distribution policy. The health emergency provides a unique opportunity for a new paradigm to mitigate between global health, national and commercial interests.
